Human COP9 developmental protein

Abstract

The present invention provides a human COP9 protein (HuCOP9) and polynucleotides which identify and encode HuCOP9. The invention also provides expression vectors, host cells, antibodies and antagonists. The invention also provides methods for the prevention and treatment of diseases associated with expression of HuCOP9, as well as diagnostic assays.

What is claimed is: 
     
       1. An isolated and purified polynucleotide sequence encoding a polypeptide comprising the amino acid sequence of SEQ ID NO: 1. 
     
     
       2. A hybridization probe comprising the polynucleotide sequence of claim 1. 
     
     
       3. An isolated and purified polynucleotide sequence comprising SEQ ID NO:2. 
     
     
       4. An isolated and purified polynucleotide sequence which is complementary to the polynucleotide sequence of claim 1. 
     
     
       5. A hybridization probe comprising the polynucleotide sequence of claim 4. 
     
     
       6. An expression vector containing the polynucleotide sequence of claim 1. 
     
     
       7. A host cell containing the vector of claim 6. 
     
     
       8. A method for producing a polypeptide comprising the amino acid sequence of SEQ ID NO:1, the method comprising the steps of: a) culturing the host cell of claim 7 under conditions suitable for the expression of the polypeptide; and   b) recovering the polypeptide from the host cell culture.   
     
     
       9. A method for detection of a polynucleotide encoding SEQ ID NO:1 in a biological sample containing nucleic acid material, the method comprising the steps of: a) hybridizing the polynucleotide of claim 4 to the nucleic acid material of the biological sample, thereby forming a hybridization complex; and   b) detecting the hybridization complex, wherein the presence of the hybridization complex correlates with the presence of the polynucleotide in the biological sample.
